First results of the Fermi Large Area Telescope

The Fermi Large Area Telescope (Fermi LAT) is a pair conversion telescope sensitive to photons in the energy range 30 MeV to >300 GeV. It was launched on June 11th 2008 and has now been successfully operating for over a year and made breakthrough discoveries in high energy astrophysics. In this seminar I will give an overview of the results from Fermi LAT and the implication it has had in astrophysics and astro-particle physics.
